[0001] The present invention belongs to the technical field of new energy vehicles, and in particular relates to a leak-proof joint device suitable for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles and hydrogen engine vehicles.

[0003] In order to cool down the batteries and electrical devices inside new energy vehicles, a liquid cooling device needs to be installed.

[0004] The existing liquid cooling device suitable for new energy vehicles needs to dismantle the pipeline during maintenance. When the pipeline is dismantled, the coolant will overflow, causing damage to the environment and wasting the coolant.

[0005] Therefore, in order to solve this problem, it is necessary to develop and design a leak-proof joint device suitable for new energy vehicles, which solves the problem of leakage in the existing joint devices suitable for new energy vehicles. Summary of the invention

[0006] In view of the deficiencies in the prior art, an embodiment of the present invention aims to provide a leak-proof joint device suitable for new energy vehicles to solve the problems in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0010] As a further solution of the present invention, a filter screen is installed on the third end surface of the adapter, and the third end surface is in contact with the fourth end surface of the filter screen.

[0011] As a further solution of the present invention, the first opening on the side of the filter screen fits with the first protrusion of the adapter, and the surface of the filter screen has a first circular hole, and a spring is installed on the fifth end face of the filter screen.

[0012] As a further solution of the present invention, a pressure plate is installed on the sixth end face of the adapter, and a first screw is installed in the first threaded hole of the adapter, and the first screw is installed on the surface of the pressure plate.

[0013] As a further solution of the present invention, the retaining frame is installed between the adapter and the pressure plate, and the seventh end face of the retaining frame and the eighth end face of the plug are in contact with each other.

[0014] As a further solution of the present invention, the threaded joint is installed on the surface of the water tank, and the second internal thread of the threaded joint cooperates with the second external thread of the water tank, the surface of the threaded joint has a second circular hole, a third circular hole and a first groove, and the threaded joint has a third external thread, and the third external thread of the threaded joint is used to install a water pipe.

[0015] As a further solution of the present invention, the diaphragm is installed in the third circular hole of the threaded joint.

[0016] In summary, compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0017] Install the threaded joint on the water tank. The plug moves toward the inside of the water tank under the action of the threaded joint, and the antifreeze in the water tank flows to the outlet of the water tank. At the same time, the plug pushes the diaphragm toward the water pipe, and the antifreeze flows into the water pipe through the second circular hole. Disconnect the threaded joint from the water tank. Under the joint action of the plug and the spring, a closed space is formed inside the water tank to prevent the coolant in the water tank from flowing out. Under the pressure of the antifreeze in the water pipe, the diaphragm can effectively block the coolant in the water pipe from flowing out.
